Yeah I’ve often wondered this also when watching Niagara Falls – it’s amazing the volume of water going over the falls every second and it never ends. It’s mind blowing when you think about it.
To move that much volume, that consistently for that long, requires a HUGE feeder area. There are likely thousands of feeder rivers and streams that dump into it all day every day. You would think it would dry up/slow down a little but it just keeps going and going.
